BACKGROUND
The presence of antimicrobial-resistant (AMR) bacteria in edible ice in tropical countries is largely unknown.
METHODS
We evaluate the presence of extended-spectrum β-lactamase (ESBL)-producing Enterobacterales in 100 edible ice samples from drink carts in 20 markets in four provinces (five markets/province) in Thailand. Ten samples of commercially sold edible ice in sealed packages were tested as controls.
RESULTS
Of 100 samples, 29 (29%) were culture positive for ESBL-producing Enterobacterales, with a median quantitative count of 2 colony-forming units (CFU)/100 mL (range, 1 to 40 CFU/100 mL). All control samples were culture negative for ESBL-producing Enterobacterales.
CONCLUSIONS
AMR bacteria is commonly found in edible ice from drink carts.
背景
热带国家食用冰中抗菌药物耐药（AMR）细菌的存在情况很大程度上未知。
方法
我们评估了泰国四个省份（每个省份五个市场）20个市场的饮料车中100份食用冰样本中产超广谱β-内酰胺酶（ESBL）肠杆菌科细菌的存在情况。对10份密封包装的市售食用冰样本进行检测作为对照。
结果
在100份样本中，29份（29%）产ESBL肠杆菌科细菌培养呈阳性，定量计数中位数为2菌落形成单位（CFU）/100 mL（范围为1至40 CFU/100 mL）。所有对照样本中产ESBL肠杆菌科细菌培养均为阴性。
结论
饮料车的食用冰中普遍存在AMR细菌。
